Hi @Andy1978

Thanks for the great tool.

I'm looking for the font that is fastest to penplot.

Such a font:

• would have a minimum number of gcode instructions
• would heavily use G02/G03 instructions

Have you ever heard about this? What do you think?

Please split the text and add some line-breaks to the "( text='...' )" G-Code output:

https://github.com/Andy1978/hf2gcode/blob/master/src/hf2gcode.c#L298

hf2gcode generated G-Code with long input texts does not work on GRBL and LinuxCNC:

• The GRBL motion controller has a line length limit (– 50 for older versions, 70 for 0.8c dev or later),
• The LinuxCNC / Machinekit NIST rs274 G-Code interpreter has a line length limit, too (– don't know the exact values but just ran into this):

Interpreter exited with error:
Command too long

Hi @Andy1978 . I've created a small GUI to preview G-Code in a more interactive manner, see:

https://github.com/koppi/gcoder and quick demo Video: https://www.youtube.com/watch?v=9D3hMXP5-QM

One thing in hf2gcode.c that needs to be changed imho is, to send the gcode data to stdout and the debug and info messages to stderr. Should I send you a pull request to make this happen?

If I try to generate g-code from an input file with line breaks, the x offset only indents the first line, but not the following lines.

e.g. hf2gcode --font=scripts -o out.nc -i in.txt -s 0.3 -y 100 -x 100

Hey Andy,

I'm having an error when building this program. I've installed the make command using Chocolatey, and when I run that command on the src folder, this is the output:

C:/ProgramData/chocolatey/lib/make/tools/install/bin/make.exe -C ../hershey_fonts src
make[1]: Entering directory 'C:/Users/techmaster/Downloads/hf2gcode-master/hershey_fonts'
./fix_linebreak.sh orig/astrology.jhf fixed/astrology.jhf
process_begin: CreateProcess(NULL, bash C:\Users\techmaster\Downloads\hf2gcode-master\hershey_fonts\fix_linebreak.sh orig/astrology.jhf fixed/astrology.jhf, ...) failed.
make (e=2): The system cannot find the file specified.
make[1]: *** [Makefile:21: fixed/astrology.jhf] Error 2

make: *** [Makefile:12: hf2gcode] Error 2
PS C:\Users\techmaster\Downloads\hf2gcode-master\src>

As you can see. it cannot find fixed/astrology.jhf. Running the make command leaves two empty folders, however. These folders are -p and fixed.

Wrong G-Code output if text input size is exactly 100 bytes:

but when I open the ngc file, it doesn't have the letters I am expecting. I am wondering what I missed. Thank you.

This is what I get:
